How to get another email address, this depends on a few things:

Who your Internet Service Provider (ISP) is and how many email addresses they allow you to have per account. If you have used all the email addresses you can have with your ISP, then you might consider a hotmail, yahoo, google, etc account. They are free and easy to setup. If not call your ISP and ask if you can have an extra email account and how much it would cost. Most ISP's allow you 5 email addresses per account. You can also get a domain name (www.mydomain.com). for an email address.
